DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning function for cleaning a floor by rotating a brush at a high speed with a motor while supplying cleaning water, and sucking waste water generated by the cleaning by a suction action of a squeegee from the floor. The present invention relates to a floor cleaning machine having a sewage suction function.

[0002]

2. Description of the Related Art A conventional general floor cleaning cleaner for cleaning a floor while pushing a handle and moving a brush head is disclosed in, for example, Japanese Patent Application Laid-Open No. 62-253020. By rotating the brush with a motor while dripping washing water toward the brush,
While the floor is brushed (washed), the squeegee is used to suck and collect the cleaning wastewater into the tank at the same time. However, if you want to use this floor cleaning cleaner differently from the original, for example, If the floor is very dirty, do not collect the detergent sprayed on the floor during brushing at the same time as brushing, leave it on the floor as it is, and use a brush until the floor is clean If you want to continue brushing and recover the sewage when the floor is clean, this machine cannot handle it.

[0003] Therefore, for example, Japanese Patent Application Laid-Open No. Hei 10-513389.
As described in Japanese Patent Application Laid-Open Publication No. H11-260, the brush and the liquid collecting blade (squeegee) in the cleaner head are moved at different heights from each other. A device was considered in which the collection was not performed, and the brush was retracted to prevent the brushing when the sewage was sucked.

[0004]

However, the above-mentioned cleaner head can perform the cleaning by the brush and the suction of the wastewater by the liquid collecting blade separately by switching, but it is not possible to perform the cleaning and the suction at the same time. Because there is no
Depending on the degree of soiling on the floor, there may be a case where a sufficient cleaning effect cannot be exerted, and there is a problem that cleaning workability is not good because the cleaner head is manually moved back and forth.

Accordingly, a technical problem of the present invention is to make a floor cleaning cleaner, which cleans the floor surface by rotating a brush at a high speed, simultaneously supply cleaning water, brush cleaning, and suction of sewage by a squeegee. Or, only the water supply and washing are performed at the same time without suctioning the sewage, and only the suction of the sewage is performed without the water supply and washing. That is to provide a function that can be performed.

[0006]

(1) In order to solve the above-mentioned technical problem, according to the present invention, a brush is rotated at a high speed by a motor while supplying cleaning water to the floor. A floor cleaning cleaner having a cleaning function of cleaning a surface and a sewage suction function of suctioning sewage generated by the cleaning from a floor surface by a suction function of a squeegee, wherein the brush and the squeegee are relatively positioned. It is configured to be able to slide up and down, and the positional relationship between these brushes and squeegees,
A floor cleaning water absorption position where both the brush and the squeegee are grounded to the floor, a floor cleaning position where only the brush is grounded to the floor and the squeegee is separated from the floor, only the squeegee is grounded to the floor, and , Sewage suction position where the brush is separated from the floor surface with the supply of washing water stopped, a total of three positions,
Or, because it was configured to be switchable to any two positions,
Just switch the relative position of the brush and squeegee,
One floor cleaning / cleaning machine is operated by switching to the same floor cleaning / absorbing state as a normal floor cleaning machine, a floor cleaning state where only brush cleaning is performed, and a sewage suction state where only sewage suction is performed. Make it possible.

(2) According to the present invention, a disk-shaped brush and a driving motor are provided in such a manner that a substantially central portion of a squeegee frame to which squeegee blades are attached at the front and back is vertically penetrated. A brush head portion comprising a squeegee frame and a squeegee frame to which the squeegee blade is attached, since the positions of the squeegee frame and the brush head portion can be relatively slid up and down,
By sliding the brush head portion composed of the brush and the motor up and down relatively, it is possible to switch one floor cleaning machine to the above three types and use it.

(3) In the present invention, the distal end of the operating handle is vertically operably connected to a brush head comprising a disk-shaped brush and a driving motor. On the other hand, the squeegee frame to which the squeegee blade is attached is provided with a handle fulcrum portion which is in contact with the distal end portion of the operation handle and serves as a fulcrum of the lever when the operation handle is operated downward. The brush head is slid upward with respect to the squeegee blade in accordance with the downward operation, so that the brush is separated from the floor, so that the brush is separated from the floor by operating the operation handle, By grounding this, one floor cleaning and cleaning machine can be used to brush the floor surface and to not brush it. Make it possible to use differently.

(4) In the present invention, a squeegee frame on which the squeegee blade is mounted is provided with a guide plate for guiding the operation handle up and down, and the guide plate is provided with the operation handle. In addition to providing a support portion that can be supported at a position upright with respect to the floor, a brush separated from the floor in accordance with the operation of the operation handle is arranged between the squeegee frame and the brush head in a separated state. Can be locked,
Since the locking means configured to be able to arbitrarily release the locked state is provided, the operating handle can be supported in a storage state standing upright with respect to the floor, while the brush is separated from the floor by operating the operating handle. Can be used in a state in which only the suction of the wastewater is performed in a state of being separated, that is, without performing the brushing.

(5) In the present invention, the locking means provided between the squeegee frame and the brush head portion may include a guide cylinder attached to a guide plate of the squeegee frame, and a root tip. A slide shaft, the end of which is slidably fitted inside the guide tube, and which is rotatably mounted on the slide shaft, and operates the operation handle downward. Then, when the brush head is slid upward, it is locked by a stopper provided above the guide cylinder to lock the slide shaft, that is, the upward movement of the brush head, on the way. When the brush handle is lowered by operating the operation handle upward, the brush is locked in the locking groove formed on the side surface of the guide cylinder, and the brush is lowered slightly from the floor surface when the brush head is lowered. After the operating handle is operated downward again to slide the brush head upward, and then operated again upward, the operating handle is engaged and rotated by the stopper. Since the locking hook is released from the locking groove, and the brush head can be lowered and the brush can be grounded to the floor, the operation handle is vertically moved by the function of the locking hook. Simply by rotating the brush, it is possible to lock the brush at a position separated from the floor surface, or to release the lock to ground the brush to the floor surface.

(6) In the present invention, the squeegee frame is pulled up to lock the squeegee blade at a position separated from the floor surface between the brush head and the squeegee frame. In addition, the provision of a temporary stopping means capable of releasing this locked state arbitrarily allows the squeegee blade to be separated from the floor surface, so that only the brush cleaning of the floor surface is performed without suction of wastewater. It is possible to make the floor cleaning machine perform the operation.

(7) Further, according to the present invention, as set forth in claim 7, the brush head unit is provided with two left and right brushes rotating in opposite directions, and two left and right brushes rotating these two brushes. Since the brush is constituted by the two motors, the brush can be rotated by the two motors in a well-balanced manner, and a strong brushing effect can be exhibited.
